If I bought a T-Mobile phone, such as the Motorola V180 from Motorola without a T-Mobile contract, would I be able to use in the U.S. and in Europe (France)? If so, could I buy a prepaid SIM card in France so the rates would be cheaper? I know the phone is a tri-band (GSM 900/1800/1900). The V180 on Motorola's site says it is $139. Is that with or without a T-Mobile contract? Do I need to buy the phone unlocked? Or does it come unlocked from Motorola (to work in other countries)? Finally, does anyone know any good websites or companies that sell tri or quad-band phones with/without contracts at a good price that isn't too expensive? Thanks in advance.
